Google Ads for law firms is the most expensive vertical on the platform
Across 23 industries in WordStream's 2026 benchmark study, attorneys and legal services sit at the top of every cost column — which is the first thing anyone running Google Ads for law firms needs to plan around:
| Legal | All industries | |
|---|---|---|
| Cost per click | $9.87 | $5.42 |
| Click-through rate | 5.87% | 6.64% |
| Conversion rate | 5.55% | 8.18% |
| Cost per lead | $131.63 | $66.69 |
A legal click costs nearly double the cross-industry median, converts worse, and produces a lead at roughly twice the price.
That's the average. The spread by practice area is far wider, and it's the number that actually decides your budget:
| Practice area | Typical cost per click |
|---|---|
| Family law, divorce | $8 – $25 |
| Immigration | $8 – $25 |
| Employment law | $10 – $30 |
| Criminal defence, DUI | $15 – $50 |
| Business law | $20 – $60 |
| Personal injury | $50 – $200+ |
Personal injury is the most expensive keyword category on the entire platform. A single click can cost more than a month of ads in most industries — because a single case can be worth six figures.
Treat these as planning ranges rather than quotes. Your actual cost depends on your city, your competition and your Quality Score.
The only number that matters in Google Ads for law firms: cost per case
Cost per click is a distraction in legal. So is cost per lead. The number that decides whether Google Ads for law firms works is cost per signed case, and you get there with two multiplications.
Cost per lead = cost per click ÷ conversion rate Cost per case = cost per lead ÷ signed-case rate
Two worked examples, same budget:
Family law. $3,000/month at $20 a click buys 150 clicks. At a 6% conversion rate that's 9 leads, costing $333 each. If 1 in 3 signs, that's 3 cases at $1,000 per signed case. At a $4,500 average fee, $3,000 of spend returned $13,500.
Personal injury. $3,000/month at $120 a click buys 25 clicks. At 5% that's roughly 1 lead at $2,400. If 1 in 4 signs, you need four months of spend per case — but a single case may be worth far more than twelve thousand dollars.
The lesson isn't that one is better. It's that personal injury cannot be run on a small budget. At $120 a click, a $1,000 month buys eight clicks and no statistical signal at all. If you can't fund enough volume to get conversions, pick a narrower, cheaper practice area or don't run search ads.
Local Services Ads usually beat Google Ads for law firms
This is the part most guides covering Google Ads for law firms underplay, and it's often the single highest-return change available.
Local Services Ads sit above everything — above the regular text ads, above the map pack. And you pay per lead, not per click.

The pricing difference is substantial. Reported LSA cost per lead by practice area:
| Practice area | LSA cost per lead |
|---|---|
| Truck accidents | $300+ |
| Personal injury | ~$240 ($140–$340) |
| Workers' compensation | ~$150 |
| Family law | ~$85 |
| Criminal defence | ~$75 |
| Bankruptcy | ~$60 |
| Estate planning | ~$50 |
| Immigration | $18 – $50 |
Compare a ~$240 personal injury LSA lead against a search lead that can run into the thousands once you account for the click price and conversion rate.
The Google Verified badge. On 27 October 2025 Google consolidated Google Guaranteed, Google Screened and License Verified into a single Google Verified badge. For law firms the requirements are an active state bar licence in good standing, professional liability insurance, a background check, identity verification, and at least one client review — personal injury firms are reported to need five or more.
What you give up: no keyword targeting, no ad copy, no landing pages. You can't optimise an LSA the way you optimise a campaign. What you can influence is your review profile, your responsiveness, and your service areas — LSA ranking leans heavily on review score, review count and how fast you answer.
A reasonable split is roughly 30–40% of budget to LSAs and 60–70% to search. Start LSA-first if you're new: the leads are cheaper, the setup is simpler, and you learn what your intake can actually handle.
Why most Google Ads for law firms campaigns waste money
Bidding on "lawyer" or "attorney" alone. These attract students,
job-seekers, people researching the profession, and other firms. Expensive
and useless. Bid on the matter, not the job title: divorce lawyer [city],
dui attorney near me.
No negative keyword list. In legal this is not optional. Minimum starting
list: free, pro bono, salary, jobs, how to become, law school,
legal aid, reddit, template, yourself, plus every competitor firm
name you don't want to pay for.
Running statewide from one office. Proximity still matters for legal intent. Tight geographic targeting around your actual catchment beats broad coverage at this click price.
Sending clicks to the homepage. At $50 a click, a page that talks about the firm's founding year rather than the specific matter is an expensive mistake. One landing page per practice area, each with the matter, the outcome, and a single clear way to make contact.
Not tracking calls. Legal enquiries come by phone. If you aren't using call tracking with a duration threshold — 60 seconds is reasonable for legal — you have no idea which keywords produce actual matters.
Slow intake. A $300 lead that gets called back the next morning is usually gone. For personal injury especially, the firm that answers first very often signs the case. Intake speed beats bid strategy.
A sensible start for Google Ads for law firms
Budget. Below about $2,000–4,000/month, most practice areas can't gather enough data to optimise. At $500/month in legal you are buying a handful of clicks and learning nothing.
Structure. One campaign per practice area, with its own budget. Divorce and criminal defence should never compete for the same pot.
Match types. Exact and phrase only to begin with. Broad match in legal, before the account has conversion data, is an expensive education.
Schedule. If nobody answers the phone at 11pm, don't pay for 11pm clicks — unless you run genuine 24-hour intake, in which case say so in the ad.
Compliance. Bar advertising rules vary by jurisdiction. Claims about outcomes, "specialist" or "expert" labels, and testimonials are all restricted in many places. Check your bar's rules before writing ad copy — Google's approval process will not do that for you.

FAQ
How much do Google Ads cost for law firms? Around $9.87 per click and $131.63 per lead on average. By practice area, clicks run $8–25 for family law and immigration, $15–50 for criminal defence, and $50–200+ for personal injury.
Are Google Ads for law firms worth it at a small firm? Yes, for practice areas with reachable click prices and a case value well above the cost per case. Family, immigration and criminal defence work at modest budgets. Personal injury generally does not without serious spend.
Local Services Ads or Google Ads for lawyers? Start with LSAs. They sit higher, cost per lead rather than per click, and are substantially cheaper per lead in most practice areas. Add search ads once intake is handling LSA volume well.
What budget do I need? $2,000–4,000/month for most practice areas. Personal injury needs far more. If your budget is below $1,000, use it on Google Business Profile optimization instead.
Why is personal injury so expensive? Case values run into six and seven figures, so firms can profitably pay hundreds per click. You're bidding against that economics.
Can I run Google Ads for law firms myself? Yes, though legal is an unforgiving place to learn. The combination of high click prices, bar compliance rules and call-based conversion makes mistakes costly. If you do, start narrow and watch search terms weekly.
